BOOKMARK Julius C. Tam, 1035 W. 8th Place, Los Angeles 17, Calif. FiledNov. 2, 1960, Ser. No. 66,858 1 Claim. (Cl. 116-119) This inventionrelates to bookmarks and it is a particular object of the invention toProvide a bookmark which may be sold separate from a book and containswithin itself the means for applying it to a book.

Certain books, especially books bound for gifts, have a ribbon bookmarkincorporated with the book when it is bound. Bound books generallyhowever are manufactured without such a ribbon bookmark.

It is another object of the invention to provide a ribbon bookmark whichincludes means for applying it to a book after the latter has beenbound.

A further object of the invention is to provide such a ribbon bookmarkin which the means for securing the same to a book forms a suitable cardon which the ribban of the mark may be wound and on which instructionsmay be printed for applying the bookmark.

The manner of accomplishing the foregoing objects as well as furtherobjects and advantages will be made manifest in the followingdescription taken in connection with I the accompanying drawings inwhich- FIG. 1 is a diagrammatic perspective view illustrating apreferred embodiment of the invention while the same is in the processof beingdisassembled for application to a book. This view also maycorrectly illustrate the invention during the assembly of the same inthe manufacture thereof.

PEG. 2 is a view similar to FIG. 1 as showing said bookmark completelyassembled as at the completion of the manufacture of the same.

FIG. 3 is a perspective view of a loose-bound book with the body of thesame opened to form a space between said body and the spine'of the bookand with the pressure adhesive strip of the bookmark of the inventionlowered suspended on the ribbon of said bookmark 'ited States Patent"ice the adhesive 22 so as to adhere thereto. A flexible strip of sheetmaterial 25 of the same size and shape as the strip 21 is appliedthereto so as to temporarily cover pressure adhesive 22, the strip 25however being of such a material as to be readily peelable from saidpressure adhesive. Opposite ends of the strips 21 and 25 have notches 26which are superimposed in matching relation when the two strips are heldtogether by the pressure adhesive 22, and these notches act as guidesfor the ends of loops 27 formed by winding the ribbon 24 about thewinding card 28 which is formed by the two strips 21 and 25 when thusassembled.

The terminal portion 29 of ribbon 24 may be tucked under the loops 27 ofthe ribbon wound on the card 28 to prevent the ribbon unwinding fromsaid card.

Exposed marginal areas 30 of the strip 25 in the finally assembledbookmark 20 as shown in FIG. 2 may have imprinted thereon instructionsfor the application of the bookmark 20 to a book 10. This isaccomplished in the following manner: Disengaging the terminal portion29 of the ribbon 24, the latter is unwound from the windiug card 28, thebook It) is opened as shown in FIG. 3,

into said space for the application of said bookmark to said book.

PEG. 4 is a vertical fragmentary sectional view taken on the line 4-4of'FlG. 3 of the book shown in this view after the said bookmark hasbeenapplied thereto said bookmark.

Referring specifically to the drawings, it is to be noted that theinvention is adapted to be applied to a loosebound book 10 the body 11of which is formed by the pages of the book which are assembled insignatures sewed together along the back edges of the latter which arethen covered by a cheeseclothsuper 12 and which is glued to coverboards13 which are covered by a sheet of cloth 14 glued thereto, a centralportion 15 .of said cloth being loose and referred to as the'spine ofthe book 10. When book it is opened a free space 16 is formed betweenthe body 11 of the book and the spine 15. v

The invention is illustrated as preferably embodied in a bookmark 2%,FIG. 2 showing this in its finally manufactured form. The manufacture ofthis bookmark is shown in FIG. 1 as including the steps of providing athereof coated with pressure adhesive material 22. An

the cover strip 25 is peeled from the strip 21 as shown in FIG. 1, andthe latter strip, suspended on the ribbon 24 is lowered as shown in FIG.3 into the space 16 with thepressure adhesive 22 preferably turnedtowards the super 12 of the book and the book is then closed andpressure applied to the spine 15 in the direction of arrows 32 in FIG. 4so as to press the pressure adhesive coated surface of the strip 21against the super 12 of the book 10 and cause the permanent adherence ofthe strip 21 to said super.

The ribbon 24 of the bookmark 20 is now free to be drawn downwardly fromthe head to the tail of the book it) between any pair of adjacent pagesof the book to serve its normal function of bookmark.

- While only a single preferred embodiment of the invention is disclosedherein, it is to be understood that various changes and modificationsmay be made in this without departing from the spirit of the inventionor the scope of the appendedclaim.

The claim is:

A bookmark for association With a loose-bound book, the spine of whichspringsback from the book body to form a space therebetween when thebook is opened, said bookmark comprising a strip of flexible sheetmaterial coated with pressure adhesive on one face thereof;

' a cover strip of like shape applied tosaid face to cover endporti0n'23 of a fabric ribbon 24 is pressed against 7 said adhesivetemporarily but readily peelable therefrom; and a ribbon, an end portionof which extends between said strips and adheres to said adhesive, saidstrips having notches in their opposite ends and uniting to form arelatively stiff, notched winding card for said ribbon, said ribbonbeing unwoundand said cover stripremoved and said pressure adhesivestrip lowered suspended on said ribbon into said space of said book andcompressed between said spine and said body to unite said strip withsaid book and anchor said ribbon to provide a bookmark for said book.
